HNO3@nano SiO2: An efficient catalytic system for the synthesis of multi-substituted imidazoles under solvent-free conditions
Concentrated nitric acid supported on nano silica (HNO3@nano SiO2) has been prepared via a simple procedure. The synthetic powder has been utilized as an effective catalytic system for the synthesis of various 2,4,5-trisubstituted imidazoles under solvent-free conditions at 100 °C in good to excelle...
